HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 421,036, dated February11, 1890. Application filed March 1, 1889- Serial No. 301,693. (Nomodel.)

To all whom, it may concern.-

Be it known that I, ISAAC D. \VEAVER, of Lebanon, in the county ofLebanon and State of Pennsylvania, have invented a new and usefulImprovement in Hose- Couplings, of which the following is a full, clear,and exact description.

My invention relates to an improvement in hose-couplings especiallyadapted for use in :0 connection with steam-heating apparatus forrailway-trains, and has for its object to provide a simple and durablecoupling, in which washers and objectionable, leaky, and interchangeabledevices may be dispensed with. A further object of the invention is toprovide a coupler capable of convenient and 6X-' peditious manipulation,and wherein there will be but little danger of the operator beingscalded in the process of uncoupling by escaping steam or condensedwater.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter more fully set forth, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis'specification, in which similar figures of reference indicatecorresponding parts in all the Views.

Figure l is a side elevation of two sec- 0 tions coupled and partiallyin section. Fig. 2 is a plan view of the coupled sections. Fig. 3 is arear elevation of the coupled sections. Fig. 4 is a front elevation of asingle section. Fig. 5 is a horizontal section through the 3 5 body ofthe coupled sections on a plane corresponding with the line main Fig. 4.Fig. 6 is a perspective detail view of the handle and bolt-head, andFig. 7 is a detail plan view of the same.

I11 carrying out the invention the body 10 of the coupling is providedwith cylindrical side extensions 11 at the outer end, and with twocircular openings 12 and 13 in the said ends separated by a verticalpartition 14 extending a short distance within the body,

which partition is usually beveled at the inner face and likewise theinner wall of the body at the opening, so that the least possibleresistance will be offered to the free passage of steam into the opposedand inter- 5o locked coupler, as best illustrated in Fig. 3.

In'the mouth of the opening 12 a concave recess 15 is formed, and a nose16, having a spherical outer surface, is projected from the outer wallto the opposite opening, as shown in Fig. 5, which nose is capable ofneatly fitting in the recessed mouth of the opening in the opposedcoupler corresponding to the aforesaid opening 12. By reason of thisconstruction when the couplers are brought together they are unitedpractically by a balland-socket joint.

From the lower surface of the cylindrical extension 11 of the bodycontaining the noseopening a housing or shield 17 is projected, whichfollows the contour thereof from the partition 14, preferably to a pointbelow the horizontal axis of the body.

A perpendicular horn 18 is formed integral with the under centralsurface of the body 10 at the front, provided with an inwardlyextendingarm 19 at the upper extremity, having a serrated surface 20, as bestillustrated in Figs. 2 and 4, and a vertical recess 21 in one side, therear wall of which is preferably concaved, as illustrated in Figs. 3 and4. Upon the opposite side of the horn, at the upper end, a socket 22 istransversely secured or ,cast integral therewith, having a conical bore,as shown in Fig. 1, capable of receiving a conical sleeve 23, integralwith the handle 24, as best shown in Fig. 6, the said handle being heldto revolve within the socket by a threaded pin 25, passed through thesleeve 23 and the rear end of the socket 22, which pin is provided uponthe rear extended end with a suitable nut 26. (Clearly illustrated inFig.

1.) The pivoted end of the handle is provided with a bolt-head 27,capable of entering the recess 21 of the horn'of the opposing coupler,go the inner face of the said bolt-head being provided with acam-surface 28, as shown in detail in Fig. 6. By reason of the pivotalconnection of the handle above described with. the horn the wear isreduced to a minimum, and only a tensile strain is brought to bear uponthe bolthead.

In the process of coupling the two couplers are brought together in suchmanner that the thimble 16 of one coupler will enter the opening 12 ofthe opposed coupler. The handles which are in process of coupling in ahorizontal position are carried downward to a vertical position incontact with the horn, whereupon the cam-face 28, being brought incontact with the outer side wall of the hornrecess 21, crowds the twocouplers together, making a firm, secure, and steam-tight joint, and thebolt-head 27, entering the said recess in the horn, securely locks thecouplers in position. gether, the lower extending serrated ends of thehorns are brought together, as illustrated in Fig. 2.

To uncouple, it is simply necessary to throw the handle upward to thehorizontal position illustrated in Figs. 3 and 4, and as the lions ing17 extends over the joint until the coup lers are carried a considerabledistance apart 'the escaping steam or hot water cannot inter-.

fere with the operator, as it is prevented from escaping downward in thedirection of the handle, and must of necessity find a vent upward.

I have described the hose-coupling as adapted for use with steam-pipes;but if it is used for other purposes, the horn and the handle may beomitted, and the sections may be held in contact in any suitable orapproved manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a hose-coupling, the combination, with a bodyprovided with openings in its end separated by a central partition, oneof the said openings being provided with an outwardly-extending nosehaving a spherical exterior and the other opening having a concaverecess in the mouth, of a shield or housing projected from the side ofthe body from which the nose projects, all combined for operationsubstantially as and for the purpose specified.

2. In a hose-couplin g, the combination, with a body provided withopenings in its ends separated by a central partition, and a noseprojected from one of the said openings and the other opening having arecess in the mouth, of a shield or housing extending from one side ofthe body under the nose, and a locking hen the couplers are lockedtodevice attached to the body at the forward end, substantially as shownand described.

3. In ahose-eoupling, the combination, with a body provided withopenings in its ends separated by a central partition, and a noseprojected from one of said openings and the other opening having arecess in the mouth, of a shield or housing extending from one side ofthe body under the nose, a locking device attached to the body at theforward end, a horn projecting from the body having a recess in oneside, a socket secured to the opposite side of the horn, and a handlepivoted in the said socket provided with a bolt-head capable of enteringthe recess of the opposed coupler and provided with one cam-shaped sideface, all combined for operation substantially as shown and described.

4. In a hosecoupling, the combination, with a body provided withopenings in its ends separated by a central partition, and a noseprojected from one of said openings and the other opening having arecess in its mouth, of a shield or housing extending from one side ofthe body under the nose, a horn proj ecting from the body having arecess in one side having a conical. bore, a handle provided with anattached conical sleeve capable of entering the bore of the socket, andan attached bolt-head having an inner cam face, and a threaded pinpassed through the handle, the sleeve thereof, and through the rear endof the socket, said pin provided with a lock-nut, substantially as andfor the purpose specified.

5. In a hose-con plin g, the combination, with a body portion consistingof two sections, each provided with a horn, of a lever pivoted to onehorn and provided with cam-head for engaging the other horn,substantially as de scribed.

6. In a hose-coupling, the combination, with a body portion consistingof two sections, each provided with. a recessed horn, the said hornsinterlocking with each other, of a lever pivoted to each horn andprovided with a camhead for engaging the recess of the horn of the othersection, substantially as herein shown and described.
